PostToolUse

PostToolUse is a hook for Claude Code from tettethu/VibeGame. Its token cost is not measured, scanned A, original, Apache-2.0.

A post-tool hook that runs a local Python script after a SendMessage tool call finishes. It is associated with the VibeGame project.

In plain words
What is it for?
Use it to run the project's teammate-message tracking script after SendMessage calls. The hook has no additional behavior described beyond that script execution.
Why use it?
It automates follow-up work whenever a message is sent through that tool, avoiding a separate manual trigger.

Hook for Claude Code

Written for Claude Code: $CLAUDE_PROJECT_DIR variable.

One of 10 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 9 are separate, each on its own page.

Security

Grade A, and why

PostToolUse scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This page is one entry in a file that holds 10. Installing the file brings all of them; each is measured and scanned on its own page.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
